CHARLES W. RAYMOND, OF DAYTON, OHIO.

BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 430,752, dated June 24:, 1890..

Application filed December 6, 1889. Serial No. 332,803- (No model.)

To all whom it may concern.-

Beit known that 1, CHARLES W. RAYMOND, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Brick-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of brickmachines known as re-pressing machines, wherein it is desirable, after the bricks have been formed in the molds, to give them asec- 0nd and final pressure by which any excess of moisture is removed, the air-pressed out, and the bricks given their final set and shape, ready to be burned or baked in the kiln.

My invention has for its object the provision of novel means for automatically lubricating the mold or compress-box at every stroke of the movable bottom, which eXpels the re-pressed brick, and its novelty will be hereinafter set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a brick-press embodying my invention. Fig. 2 is an enlarged plan view of the compress-box and its movable bottom. Fig. 3 is a sectional view through the dotted line a: no of Fig. 2. Fig. 4 is ap enlarged detail section of the lower corner of the compress-box.

The same letters of reference are used to indicate identical parts in all the figures.

The press illustrated in Fig. 1 is substantially the one described in my prior patent,

No. 854,226, of December 14,1886, though it may be of any suitable construction, and in describing it generally it is only necessary to say thatA is the frame; B, the head-platen; O, the carrier having the compress-box D mounted thereon, and E the toggle-levers for ra'isin g and lowering the carrier and compress-box and actuated by the lovers F and connecting-link G II.

I is the leg passed up through the carrier and having secured upon its upper end the movable bottom J, fitted within the com pressbox. Upon the downstroke of the compress box this leg is arrested by the cross-frame K to cause the bottom J to travel up in the compress-box flush with its top to expel the pressed brick and to receive another brick to be pressed, which settles within the compressboX as the latter is lifted, as will be readily understood.

The compress-box has a steel lining L, behind which, in the body of the box near its bottom, is a groove at, extending horizontally around the box, and opening from the groove a are a number of perforations Z) through the lining L into a second smaller groove 0 in the face side of the lining and extending horizontally around the same. Just beneath the groove 0 is a second groove cl in the face side of the lining and extending horizontally around the same. The bottom J in this instance is' bound by a steel band M on its edge, secured by screws 6, and having a groove fin its outer face and extending entirely around it. This groove is of sufficient size that when the bottom is down to its lowest limit of stroke, as in Fig. 3, it registers with both the grooves c and d, and it is filled with cotton waste or other absorbent packing. The groove a is also preferably supplied with absorbent packing.

N N are two oil-cups of any suitable construction, communicating by pipes g with ducts h, through the sides of the compress box and opening into the goove (t. It results from this construction that the oil from the cups N completely fills the groove a and passes through the perforations 1) into the groove 0, and saturates the packing in the groove f, so that upon every upstroke of the bottom J, or, more properly speaking, downstroke of the compress-box and its return to its normal position, the face of the lining L is lubricated by the packing in the groove f.

The purpose of the lower groove (Z is to prevent waste by catching any oil, that may flow out from the groove 0 during the upstroke of the bottom J, which oil upon the return of the bottom J, is at once absorbed by the packing in the groovef.

Vhile I have shown two oil-cups, it is evident that any number or any source of oilsupply which constantly communicates with the groove to may be employed.

Having thus fully described my invention, I claim- 1. The combination with the compress-box D, provided with the oil-groove a and with the lining L, having perforations Z) and oilgrooves c and d, of one or more oil-cups N, communicating with the said oil-groove a and the'bottom J, having the steel band M, provided with the groove f of proper size to register with the said oil-grooves c and d when the bottom is at the lower part of the box, substantially as described.

2. The oo1npress-box D, having the lining L, With perforations I) through the same into a groove 0 on the face of the lining and into a groove CL behind said lining, and communicating with a source of oil-supply, said lining also having a second lower groove (Z, in combination with the bottom J, having a groove f in its edge, containing absorbent packing, said groove f registering With both the grooves 0 (Z When the bottom J isin thelower part of the box, substantially as described.
